ROCKVILLE, Md.--(BUSINESS WIRE)--March 2, 2004

Benchmark Performance and Scalability of Next-Generation Wireless

Edge Routers with a Single Application

Spirent Communications(TM) (LSE: SPT)(NYSE: SPM) announced today a test solution that will assist network equipment manufacturers and service providers in the roll out of next generation wireless networks. Spirent's GPRS Performance Test System SE is the first carrier-scale solution that can test and measure equipment performance benchmarks and validate system scalability. It also can measure call set-up performance and automate regression testing. The product was developed with Spirent's partner, Scientific Software Engineering Inc. (SSE), a leading provider of software-based telecommunications products.

Spirent's GPRS Performance Test System SE is built on the company's Mobility 2500 test platform. It is the only system to combine GPRS Tunneling Protocol (GTP) control and data plane traffic within a single consolidated test application. For Service Providers, the product can identify performance ceilings, facilitate vendor selections and enable accurate capacity planning.

"We are glad to be getting a test tool like this for our lab, so that we can perform industry benchmarking tests for scaling GPRS networks," said Carsten Rossenhovel, managing director at EANTC AG -- European Advanced Networking Test Center, an independent test lab based in Berlin, providing conformance, performance and interoperability tests for manufacturers and service providers. "There is a real need in the industry to understand how real next generation wireless networks will be behave at their capacity limits. With all the demand for 2.5G and 3G services and competition for those customers, performance can be a key metric to create subscriber demand and retention."

Spirent's GPRS Performance Test System SE has a wide range of protocols and emulation packages. It can simulate next generation GPRS, EDGE and UMTS mobile traffic loads, capabilities that address the critical need for accurate and repeatable benchmarks and for identifying capacity capabilities. The GPRS Performance Test System SE application can establish 32,000 GTP tunnels per second. It scales up to 12 million simultaneous GTP tunnels. Additionally, GPRS can emulate real mobile subscribers, performing activations, handoff, connection-oriented bearer traffic, session deactivations, and provide detailed statistics and diagnostics reports on each.

"Our new GPRS Performance Test System SE expands the company's wireless test solutions, including integrated wireline and wireless solutions," said Mark Fishburn, vice president of technical strategy of Spirent Communications. "With the rapidly growing next generation wireless market, this latest testing innovation will help our customers expedite their time to market and enable faster adoption and mass deployment of 3G services."

The GPRS Performance Test System SE will be available early Q2 2004.
